I think Pacific Rim looks terrible tbh, looked like a big budget Power Rangers to me.

Man of Steel definitely looks more appealing but WBs would have probably looked and though the last Superan film wasn't well received and we have to make this film dye to the court ruling (which could turn out to be a blessing in disguise for them) etc and looked at Pacific Rim it's huge, it has giant robots and aliens (toys), Transformers ade shed loads this looks like Transformers etc so you couldn't really blame them when you look at those reasons for prioritising Rim. After all they're in it to make money.
